Additional mpv configuration is possible by creating a standard mpv.conf in the application's mpv home directory. Standard mpv options and plugins/scripts are supported, with some exceptions (eg. keyboard+mouse mapping, and some others (TODO)).

See the mpv configuration documentation for the full list of options and file formats.
